Title: Cherry Bonus III- need help with repairs. Post by: RGTFanatic on August 19, 2012, 05:47:40 PM Hi all, As this is my first post I think it's best to just jump in head first.
I inherited my Father's Cherry Bonus III arcade style unit recently. The last time it was used (several years ago) everything worked fine. After transporting it to my home I have found some major problems. -When powering on I can hear the bill acceptor activating. I can also hear the monitor start to warm up. After that nothing happens.........although the bill acceptor will take a $20 bill. I have found one power switch inside the cabinet and one on the rear ....these function correctly. There are 3 standard glass fuses......all are in good shape (continuity tested). I know nothing about these machines. I am however fairly capable with electrical circuits and PCB's. If anyone can, I sure would appreciate some help figuring this out. I know it won't be a "one flip" cure, so I'm prepared to supply any info/pics you may need. Thank you so much in advance Ryc Title: Re: Cherry Bonus III- need help with repairs.

Also, check the battery for leaking and damage to the board. Title: Re: Cherry Bonus III- need help with repairs. Post by: RGTFanatic on November 05, 2012, 10:46:42 PM Thank you Channelmaniac, my battery is indeed bad (heavily corroded on the negative side). The battery is a Varta 3/v60r. I cannot find a replacement online, but have been told that a 3/v80h is a suitable replacement.
I have also looked at many master boards for sale, but they are all different from mine. My battery is mounted on a secondary PCB that is plugged into the main board via one of the 40-pin slots.........does this make a difference?? When replacing the battery, are there any important procedures I should know? any adjustments to be made after the battery install?? Thanks again very much Ryc Title: Re: Cherry Bonus III- need help with repairs.

When you are putting a machine or board in storage you should always remove the battery or it will leak. You can buy the short CB3 board, your board was a conversion from a F5 to a CB3 that's why you have that kit on it.
